Hi,

How can I set up the QCA9377 so as to be able to connect my device to 2 networks on both bands, simultaneously ?

I need to set my device as an access point (AP) on one of both bands and I need to set an Ad Hoc connection (STA) on the other band.

I do not find any tutorial to do this. The guide "80-YC636-1_E_QCA6174A_QCA9377 WLAN AND BLUETOOTH ON LINUX X86 PORTING GUIDE.pdf" has a section to set a SAP-STA connection but on the same channel while I would like to use both channels (one for SAP, and the other for STA).

Is it possible (at first glance yes) ?  If yes, how can I do that ?

Thank you.

Hi Alex,

Yes, it's possible.

But there is single radio on QCA9377 so it will do time multiplexing between 2 bands and impact throughput quite a lot.
So, if your throughput requirements are not too much, you can run STA and SAP in 2 different channels/bands.

Thanks.
